Voice biometrics is a modern technology that significantly simplifies interactions with large companies and protects against financial crimes. It is based on the unique characteristics of each person's voice, which allows for reliable user identification. This approach allows companies to effectively prevent fraud and improve customer experience. The use of voice biometrics is becoming increasingly relevant with the growth of online services, ensuring security and convenience when interacting with financial institutions and other organizations.

Fingerprints, hand vein patterns, retina and iris, and voice—all these characteristics are unique to each person. Even gait has individual characteristics, making it unique. The uniqueness of this biometric data is used in various fields, such as security, identification, and medicine. Each of us has our own set of unique features, which allows us to reliably distinguish one person from another.

These parameters play a key role in biometrics.

Biometric parameters are divided into two categories: physiological and behavioral. Hand veins are considered physiological biometrics, as they are an anatomical characteristic of a person. Similarly, the retina also falls into this category. However, when it comes to the voice, caution is advised. The voice can be considered a behavioral factor, as it depends on individual habits and articulation characteristics. Therefore, it is important to consider that biometrics includes both immutable physiological characteristics and modifiable behavioral aspects. The expression "shaky voice" is familiar to many of us. You've probably experienced this sensation during your first public speech, an awkward date, or even during a face-to-face phone conversation on crowded public transportation. Indeed, our voice is influenced not only by physiological factors but also by our emotional state. Emotions can significantly alter the timbre and tone of the voice, which sometimes becomes noticeable to the other person. Understanding this can help us better cope with anxiety and manage our voice in various situations. To reduce the influence of emotional state on the assessment results, voice biometric algorithms analyze approximately 80 different voice parameters. This approach improves identification accuracy and ensures system reliability, making voice biometrics a more effective tool for user authentication.

Biometrics performs two key functions: identification and authentication. Identification verifies a user's identity based on biometric characteristics, such as fingerprints, irises, or face. Authentication, in turn, confirms that the user is who they claim to be using the same biometric data. These processes play an important role in security systems and access to various services, ensuring a high level of protection and convenience for users.

Identification is the process that answers the question "Who is this?" For example, when a call comes into a contact center from an unknown number, voice biometrics allows us to determine the caller's identity. This process compares the caller's voice with a large array of biometric data stored in our system. Thus, voice biometric technologies provide a high degree of accuracy and security in user identification, which is especially important for protecting personal data and preventing fraud.

Authentication is an important process of confirming identity. In this situation, we assume who is calling, but additional verification is necessary. It is important to verify that the person on the line is indeed Ivan Geraldovich Petrov, born on February 24, 1963. This step prevents fraud and ensures the security of the interaction. Authentication helps us protect personal data and ensure a trusting relationship between the parties.

We already have a hypothesis about the caller's identity, so it is sufficient to compare their voice with the biometric data sample we store. This enables effective identification and ensures a high level of security.

The sample is a template or imprint left by the client. To use such a sample, the client's consent is required.

Collecting imprints is a complex process. Government agencies are currently developing a Unified Biometric System (UBS). A biometric imprint registered with one bank will allow other financial institutions to use it. This will provide additional protection for your funds from fraud and simplify the process of accessing banking services. The creation of the UBS will be an important step in improving security and convenience for bank clients.

Evaluating the return on investment for implementing a voice biometric system is fairly straightforward. By averaging customer requests and analyzing proposals from vendors, we can estimate the implementation costs to be approximately 10 million rubles. This amount is an average and may vary depending on the level of integration with the client's existing IT systems. It's important to keep in mind that exact costs may vary depending on the specifics of the project and the technologies chosen.

Consider RosEvroBetonSvyazKapital Bank, where the client identification and authentication process takes just one minute. A bank operator then resolves the client's problem or question within approximately four minutes. This approach significantly improves service efficiency and enhances the customer experience, making the bank more attractive to users. Rapid identification and high-quality support play a key role in increasing customer satisfaction and building trust in financial institutions.

RosEvroBetonSvyazKapital management sets salaries for contact center agents at a level consistent with market standards. Specifically, the salary is 50,000 rubles per month for 160 working hours, which equates to 9,600 minutes of operator work. This allows us to maintain competitiveness in the industry and attract qualified specialists, ensuring high-quality customer service.

Dividing 50,000 rubles by 9,600 minutes, we get the cost per minute of your operator's work - 5 rubles. This is an important metric that allows you to evaluate the effectiveness of labor costs and optimize your budget. Understanding the cost of labor time helps make more informed decisions in resource management and increasing productivity.

The implementation of voice biometrics at RosEvroBetonSvyazKapital allows us to reduce the time spent on identification and authentication by one minute. This means that even with a relatively small number of calls per day, say 5,000, you can save 5,000 minutes. Using voice biometrics not only speeds up the customer service process but also increases security and convenience, which is an important aspect for modern companies.

For a standard voice biometrics system installation with an investment of 10,000,000 rubles, an average payback period of 13 months can be expected. This is quite an attractive figure.

Citizen identification technology is of interest to the government. A prime example is the UIDAI system in India, which is used to identify citizens and residents. This system stores approximately 1.15 billion biometric data, which represents approximately 85% of the country's population. This approach to identification significantly simplifies accounting and management processes, ensuring security and access to various government services.

In 2016, active discussions began in Russia about the creation of a Federal Information System of Biometric Accounting (FISBU). This system is designed to search for criminals using biometric data, such as iris patterns and body tattoos. Gait identification is planned to be implemented in the near future. This functionality is expected to be implemented in 2021. FISBU will become an important tool in the fight against crime and will improve the effectiveness of law enforcement agencies.

In 2017, Sberbank invested 260 million rubles in a voice biometrics project. The bank's management stated that this project is expected to achieve a return on investment within two years of its implementation. Investments in voice biometrics highlight the growing interest of businesses in innovative technologies and their ability to improve customer experience and enhance transaction security. The implementation of such systems can significantly reduce the risk of fraud and speed up the customer identification process, making the project strategically important for the bank.

Pochta Bank's voice biometric system successfully protected the bank's funds, preventing fraudulent attacks totaling approximately 10 million rubles. This technology provides a high level of security by analyzing unique customer voice parameters and effectively detecting fraudulent attempts. Thanks to Pochta Bank's innovative solutions, users can be confident in the security of their funds and personal information.

Banks such as Alfa-Bank, Home Credit, and Tinkoff are represented in the Biometric Club. These financial institutions have already successfully implemented biometric technologies in their customer services, enhancing security and user convenience. Using biometrics in customer service facilitates faster and more efficient identification, improving the overall banking experience.
